Vim has a very powerful built-in sort utility, or it can interface with an external one. In order to keep only unique lines in Vim, you would:
:{range}sort u
Yes, it's that simple.
You could create a range in advance, such as 'a,.
(from mark 'a' to the current line) or you could create one on-the-fly using visual selection by pressing ':' in visual mode, after selecting the text you wish to sort, to get a range of '<,'>
on the command line.
If you like using an external sort utility instead, you can do it just as easily. For example, Unix sort, removing duplicate lines:
:{range}!sort -u
Many other systems also have an external sort utility, but the options and capabilities will differ. It is probably better to use the built-in Vim sort unless you are looking for a specific feature of the external sort (or using an old Vim without the :sort
command).
Examples[]
Sort in reverse[]
:%sort!
Sort, removing duplicate lines[]
:%sort u
Sort using the external Unix sort utility, respecting month-name order[]
:%!sort -M
("respecting month-name order" means January < February < ... < December)
Numeric sort[]
:sort n
(this way, 100 doesn't precede 20 in the sort)
Sort subsections independently, in this example sort numbers between "start" and "end" markers[]
:g/start/+1,/end/-1 sort n
It is very important that the strings "start" and "end" ONLY appear as markers!
Sort only specific lines using ranges[]
sort lines 296 to 349, inclusive
:296,349sort
Sort by pattern[]
When working with Javascript ES6, it may be useful to sort your imports
import './ProjectTemplateEditModal.scss'; import * as _ from "lodash"; import Moment from 'moment'; import React from 'react'; import { Button, Col, Modal, Row, Label } from 'react-bootstrap'; import { CurrencyControl } from '../../Core/Components/Controls'; import { DynamicModalMixin } from '../../Core/Components/Modals'; import { ProjectTemplateStore } from '../Stores/ProjectTemplateStore'; import { StoreBinder } from '../../Core/Utils/StoreBinder'; import { TextAreaControl } from '../../Core/Components/Controls/TextAreaControl'; import { TextBoxControl } from '../../Core/Components/Controls/TextBoxControl'; import { TooltipWrapper } from '../../Core/Components/Tooltips/TooltipWrapper'; import { withRouter } from 'react-router';
It is possible to pass a regex expression to sort. Any lines that do not match the expression will be sorted normally, while lines that do match will be sorted on the text that *follows* the expression.
:{range}sort /\/[A-z]/
This will organize your imports relative to the "package" they are related to:
import * as _ from "lodash"; import Moment from 'moment'; import React from 'react'; import { Button, Col, Modal, Row, Label } from 'react-bootstrap'; import { withRouter } from 'react-router'; import { CurrencyControl } from '../../Core/Components/Controls'; import { TextAreaControl } from '../../Core/Components/Controls/TextAreaControl'; import { TextBoxControl } from '../../Core/Components/Controls/TextBoxControl'; import { DynamicModalMixin } from '../../Core/Components/Modals'; import { TooltipWrapper } from '../../Core/Components/Tooltips/TooltipWrapper'; import { StoreBinder } from '../../Core/Utils/StoreBinder'; import './ProjectTemplateEditModal.scss'; import { ProjectTemplateStore } from '../Stores/ProjectTemplateStore';
You can also sort on text that *matches* the regex by including the 'r' flag, for example:
:{range}sort /\/[A-z]/ r

TO DO
- Probably need some general
:sort
command info. - Give examples of numeric sort and using regex sort.
- Clean up my "see also" list. It's useful now for a comprehensive list of related tips, some of which need work. At least should add a note on point of tip.
- If we're going to mention an external sort tool, we may as well include the following with a brief explanation. Vim could do this, but only with a complex regex. Or perhaps better, mention it in VimTip374 or VimTip923 in "see also".
-k2
sorts on the second field (word by default).
:!sort -k2
This misguided snippet was added recently:
- delimit the column using some char here I have | symbol as delimiter, once did with that you can use below command to sort specific column use -n if u want to sort numeric and its working on some version of vi and not on ubuntu vi :(
/|.*|/ | sort
- used to match a patern |.*| used to match words delimited between || and | as piping commend and sort to sort
This is wrong and should never work. Here's what it is actually doing:
/|.*|/
: jump to the next line that has two '|' characters in it, anywhere
|
: command separator, this lets you start a new command on the current line
sort
: do a default sort of the entire buffer
Basically this is the equivalent of typing :%sort
.
Now, what you CAN do, is provide a pattern that the :sort
command will skip over and ignore at the start of every line while sorting. For example, to sort based only on text after the last '|' character on the line (what I think was intended by the example), you'd do this:
:sort /^.*|/
